But I was hoping to use the concept to also change screens displayed. For a number of possible uses (change screens depending on season... etc)

ie:

Water Sensor detects water:

Check all connected clients and update their screen (force to status screen with red background for alert) Set a flag so we don't reset the screens again for this event.

Then on the clients:

Any button click on the HSTouch device that changes a screen (iPad, PC, etc) such as changing to screen "scrnMain" displays instead "scrnMainRed" when the event is active (in this case while the water sensor is triggered).

I do this with events too. For example, at the top of the hour, I display the calendar. 20 mins later, display the weather, etc. The family like the screens cycled through.
